Answer:
A is the correct answer.
Step-by-step explanation:
As stated in your problem, rotation only means to turn or pivot. Knowing this, one should recognize no angles are being changed and no lengths are being added. In fact, we are only changing the coordinates of each variable.
A. is correct because congruent means the same size and shape and we are keeping the same size and shape.
B. is wrong because no angles are being added or changed.
C. is wrong because no lengths are being added.
D. is wrong because no lengths are being shortened.
